Existence of non-constant curvature metrics on RP^2 with ω1=ω2=ω3 equal to twice the systole
Determine whether there exist Riemannian metrics g on the real projective plane RP^2 such that the first three widths ω1(RP^2,g), ω2(RP^2,g), and ω3(RP^2,g) all equal 2·sys(RP^2,g), where sys(RP^2,g) denotes the length of the shortest non-contractible loop, and yet the metric g does not have constant sectional curvature.

Remark 4.1. We do not know of any examples of RP with ω = ω = ω1= 2 2sys that do not have constant curvature.
